Area code 825 is an overlay code serving the entire province of Alberta, Canada, including major cities like Calgary, Edmonton, Red Deer, and Lethbridge. Introduced in 2016 as an overlay to the original 403 and 780 area codes, 825 was created to accommodate the growing demand for new phone numbers across the province. Alberta is a major hub for Canada’s energy sector, especially oil and gas, with Calgary serving as the financial and corporate center of the industry. Edmonton, the provincial capital, is known for government institutions, education, and manufacturing. The region also features rapid suburban growth, a rising tech presence, and abundant outdoor recreational opportunities in the nearby Rockies. Businesses adopting 825 are tapping into a province that blends entrepreneurial energy, natural resources, and urban expansion. With no geographic boundaries within Alberta, 825 is commonly used for mobile numbers, new business lines, and VoIP systems across both major cities and rural areas.
